SLIDE.

To all whom it may concern:

Be it knownthat I, WALTER P. SMITH, a citizen of the United States, residing at Cranberry Lake, in the county of St. Lawrence and State of New York have invented new and usefullmprovements in Slides, of which the following is a specification.

In transferring logs from a forest to a mill a continuous trough, known as a slide is employed. Any desired number of logs are hitched end to end and drawn by draft animals through the slide The slide is generally in the nature of a V-shaped trough and in temperate weather must be lubricated to facilitate the travel of the logs therethrough.

This lubrication is an expensive item both in thecost of production and the labor of application. In winter frost is permitted to accumulate on the slide to produce an ice crust which serves as an anti-friction agent between the slide and logs. These slides exposed to the elements frequently warp and the side members thereof are-thus brought out of alinement. As a result the projecting ends of the said sides interrupt the free passage of the logs. The slide must be constructed to comply with the nature of the land on which it is laid, so that parts of the said slide are arranged at angles and others at curves. To properly lay a slide requires a great amount of time and labor, and in every class of such slides with which I am acquainted the desired amount of friction between the logs and the said slides can not be successfully accomplished except at a great cost. It is therefore to be considered the primary object of this invention to produce a slide for conveying logs from a forest to a mill, that is made up of sections including tie members that have removable antifrictional rollers thereon, side members which interlock with the ties and rest on the said ties to the opposite sides of the roller,

Atdesired intervals upon the surface on which the slide is to be erected, I arrange sleeper'members or ties. Each of the ties comprises a flat base 8 having its ends formed with upstanding flanges9 that are approximately centrally formed with inwardly extending substantially rectangular is a similar view of one of the side boxings indicated by the numerals 10 and 11 respectively. The base 8 between the box- 1 mgs 10 and 11 is cut away or otherwise provided with a substantially rectangular opening which is designated by the numeral 12. On the upper face of the tie between the boxings 10 and 11 are secured longitudinalv cleats 1313. These cleats have their ends cut at an inclination, as indicated by the numerals 14, the inclined cuts being directed toward the center of the opening 12' and, of course. toward the inner faces of the cleats 13.

Both of the boxings 10 and 11 are provided with grooves 15 and these grooves form bearings for short shafts or trunnions 16 on the ends of anti-friction rollers 17. The rollers play free between the cleats 15, and preferably the inner corners of the said cleats are cut at an angle so that bark, chips or dirt from the logs traveling over the roller will not interfere with the free rotation thereof and will find an outlet through the opening 12. The boxing 10 has its bearing opening either closed to the outer face of the said boxing or straddled by a transverse member which may be arched, but the bearing opening in the boxing 11 is open to the outer face of the said boxing. Slidably mounted on the boxing 11 is a cover plate 20 having an elongated opening 21 there through and a headed stud 23 has its shank passed through the opening and secured to ei her t e being 11. or $9 th fl ge 9 at jacent the said boxing. This cover plate closes the bearing opening and prevents the accidental removal of the roller from its bearings.

The slide also includes side members which are all of a similar construction and which are generally designated by the numerals 24. The sides are beveled inwardly from their outer corners as indicated by the numerals 25 and have their inner corners provided with substantially V-shaped notches :26. These notches receive the angle ends 14 of the cleats 13. The ends of the sides 24; outward of the notches 26 are provided with slight projections 27 that contact with the sides of the boxings 10 and 11 and hold the sides 24 out of contact with the rollers 10. By reference to the drawings it will be noted that a certain amount 0f play is permitted between the cleats 13 and the sides 2%, when the said sides are arranged upon the cleats, and this play is sufficient to form curves in the slide at desired points. The ends of the sides 24; also engage with the edges of the cap plate 20 to insure the same against accidental movement to uncovering position with re spect to the trunnion of the rollers.

Between the sides 24%, and resting on the ties 8, as well as contacting. with the outer edges of the cleats 13 are the bottom boards 28 of the slide.

lVhen the device is laid the sides and bottom 28 may be spiked or otherwise effectively connected to the ties. The rollers 17 are so spaced that the logs contacting there with freely travel through the trough-like body of the slide. The slide needs no lubricating. On down-grades certain of the rollers 17 are removed from their bearings so that a greater friction is created between the logs and the slide which renders the logs under perfect control of the operators, and it is thought, from the foregoing description, when taken in connection with the drawings, the simplicity of the construction and the advantages thereof will be readily apparent without further detailed descrip tion. 7

Having thus. described the invention, what is claimed as new, is

1. A slide of the class described comprising ties having transverse cleats thereon and having their ends formed with upstanding flanges, side members notched to engage with the ends of the cleats resting upon the ties, and bottom members resting on the ties between the side members.

2. In a slide for the purpose set forth, ties, side members having beveled inner faces resting on and interengaging with the ties, and base members resting on the ties between the side members.

3. A slide for the purpose set forth, comprising spaced ties, anti-frictional rollers thereon, interchangeable side members having interlocking engagement with the ties to the opposite sides of the rollers thereon,

and base members resting on the ties "be tween the s1de members.

4. In a slide for the purpose set forth,

spaced ties each including a flat base having 7 its ends formed with upstanding flanges and boxings centrally arranged on the inner faces of said flanges, said tie between the flanges having an opening therethrough, cleats to the opposite sides of the opening and said cleats having angle ends, a roller having its ends provided with short shafts journaled in the boXings, means for removably sustaining said roller =journaledv in said boxings, interchangeable side members each having a beveled inner face and its inner corner notched and resting on the ties in contacting engagement with the flanges, the boxings and the beveled ends of the cleats, and base members supported on the ties, contacting with the cleats and arranged between the side members.

In testimony whereof I affix my signature.
